T @ZZ whomJ t r11/city concern: Be it known that L'ARTHUR W. GRANT, a' Vcitizen of the United States,residingat Springfield, in the county of Clark and State of Ohio, have invented certain new and useful Im4 f Y provements in Devices for Equipping Vehi.

cle-Wheels with Rubber Tires, of which the following is a specification. l

gMyin'vention relates to improvements in A1o vdevices for equipping vehicle-wheels with` rubberiires, this application being a division of mypending application, Serial No. 669,335,

' filed February 7, 1898.

. My invention relates particularly to that class of rubber tires ywhich are held in place on the peripheries of vehicle-wheels by an endless retaining band or bands which pass through the rubber, the rubber being seatedI My invention consists in constructions and combinations of parts hereinafter described, and set forth in the claims.

., In the accompanying drawings, Figure l is 3o a plan View of a device embodying my inven tion. Fig. 2 is a plan View showing a slight modification of the same. Fig. 3 is 'av sectional view in detail of Fig; 1. Fig. 4 is a small detail of Fig. 2. Fig. 5 is a view of a device for joining the ends of the wires.l

' In equipping a wheel with rubber tires by my improved process I take, preferably,

' though not necessarily, a single strip of rubber, through which is placed a retaining band If more than onepiece ot' rubber is employed, they will be threaded on the retaining-wires andl closed up to form substantiallyacontinuous strip. The retainingband 4 or bands are left suiiciently long to project Gribauds overlapped.' The respective ends of theband or bands are then clamped in VfromA which to form these bands. These bands are clamped by clamps d and d', which are 6o supported on bars eand e. Connecting-screws e2 pass through one of these bars and engage threaded nuts e3 in the other bar. By turningthe screws e2 so as to cause the bars e' and e to approach each other rthe bands inlay1 be 65 drawn to any degreeof tightness, the-ends of the rubber resting against the respective bar.

Inasmuch- .as the rubber is slightly'y longer than the periphery of the wheel, the rubber will be compressed'lengthwise'as the wires 7o are tightened, so as to draw the rubber in the channel. Y This compression is necessary to provide for the closing of the space'at the point where the joining is made in; the retaining`-wires.` lVhen the bands have been suiiiciently tightened 'so as to drawthe rubber rmly in the channel, the ends of the wires are cut off to the proper length and united together. This may be accomplished in any suitable and well-known manner-such as braz- 8o ing, soldering, twisting, or by intermediate connecting devices, such as a screwth'readed sleeve,or in any other manner whichwilll readily suggest itself.

In Fig. 5 I have shown the wires twisted, a 85 twisting-headfbeing employed, havinga slotV f', adapted to lit over the overlapping ends of the wire in such a manner that as the head is rotated the free ends of the wire will be twisted together. By thus twisting;r the re- 9o spective ends a splice something like the .splice in a telegraph-wire will be formed by what is known as' a right-and-left.twist. For this purpose the headf' may be provided Iwith openings f2 on its periphery, into which 95 a wrench or other suitable device for-turning the same may be made to engage.

I have shown the screws e2 passing through nuts or sleeves e3, which are tapered on the outer peripheries and t in tapered seats in the bar e'. The bar c' is slotted, as shown in e4, so that the screws e2 can pass through the slots; but when the tapered sleeves or nuts are fitted in the openings, said nuts being of larger diameter than. the slots, they will be held in the bar.

In Figs. 2 and 4 I have shown the device modified, in which the bars e and c are caused to tighten the band or bands by pressing the said` bars apart instead of drawing them together. In this construction I have preferably employed on eachv bar two clamps h and hf, which are adapted to project Within the wheel-channel and engage the retaining-4 Wires. The clamp h on the bar d has a long Jaw, which at its ends engages the outer bands, and there are intermediate openings .in same to admit of the loose passage of the inner bands, as shown in Figs. 2 and 4, and the clamp vfon the bar c has a short jaw, the ends of which engage the inner bands, as shown in Fig. 2. When the tire, with the band or bands, is in place Within the rim, the band or bands at the ends thereof are first engaged by the clamps h on the respective bars, theV jaws of said clamps 7i. when so engaged being adapted to allow the other ends of the band or bands to pass or slip through the same, and loosening the jaws of the clamps h', so that the band or bands will slip through same, and forcing the bars apart by the screws c2 the bands will be tightened and the tire compressed in the channel at the same time. After they have been sufliciently tightened the clamps h on the respective bars are tightened and the clamps 7L released. This frees the respective ends of the bands and clamps the bands at a point removed from the ends, so thatby placing the twisting device midway between the bars the ends of the bands may be twisted together by a few turns ofthe twisting device, the free ends being held in position by clamps h h, but permitted to move longitudinally to compensate for the material taken up in twisting, or the bands may be severed midway between the bars and joined together by- Welding, brazing, or by the connecting devices before described.

Having thus described my invention, I claiml. The combination with the screw-th readed rods and the cross-bars, of band-holding clamps connected to the bars, one of said bars being provided with slotted openings and tapered seats, and tapered nuts on said screwthreaded rods adapted to iit in said seats, substantially as and for the purpose specified.

2. The combination with the screw-threaded rods and the cross-bars, of a double set of clamps on said cross-bars, one set of said clamps being adapted to holdthe band, or bands, in tightening the same, and the other set to hold the same after they have been tightened substantially as specified.

3. The combination with a channel-rim, a rubber tire therein,and a band,or bands, passing through said wire, movable bars, each ot' said oars being provided with a double set of clamping devices, one set of said clamping devices being adaptedto engage the ends of said band, or bands, and the other set to engage the said band, or bands, at a point removed froi'n the ends, and means for forcibly moving said bars to cause the clamping devices to recede from each other substantially as specified.

4. The combination with a channelriin, a rubber tire therein,having the band,or bands, extending through the same, movablel bars each having a double set of clam ping devices,

one se't of said clamping devices being adapted to engage the bands at the ends thereof and the other set at a point removed from the ends thereof, and a twisting device adapted to engage said bands between the said clamps, substantially as and tor the purpose specified.

5. The combination with the crossvbars having the clamping devices,sci'ew-threaded rods extending through said cross-bars, one of said cross-bars being provided with tapered openings, and tapered nuts fit-ted in said openings, said tapered openings being slotted to permit the screw-threaded rods to pass through when the tapered nuts are removed t' rom said bars, substantially as specified.

In testimony whereof I have hereunto set my hand this 16th day of September, A. D.
